Sensing and Imaging Biomolecules with Plasmonic Nanoparticle Assemblies Coupled with Darkfield Microscopy
Noble metal nanoparticles exhibit unique optical properties arising from the resonant oscillations of their conduction electrons with light. This phenomenon is called localized surface plasmon resonance (LSPR). The LSPR frequency is extremely sensitive to the size, shape, refractive index at the …

The Self-Assembly, Optical Response and Stretch Tunability of Plasmonic Nanoparticle Monolayers
The optical properties of self-assembled plasmonic nanoparticle monolayers of varying den sities are explored. These particles are sensitive to changes in their local environment and proximity to other particles. By altering these factors, the appearance of nanoparticle assemblies is changed, …

PLASMONIC NANOPARTICLES AS VERSATILE NANORULERS FOR SENSING APPLICATIONS: DEVELOPING THE NANOPARTICLE-ON-MIRROR ARCHITECTURE
The basis of plasmonic sensors is the resonant coupling between the oscillations of free electrons, called plasmons, and incident visible light waves. By confining these oscillations within a nanostructure, the coupling efficiency is enhanced by the creation of localized surface plasmon resonant …

Thin-Film Polymer Nanocomposites Composed of Two-Dimensional Plasmonic Nanoparticles and Graphene
Plasmonic polymer nanocomposites contain plasmonic nanoparticles that are dispersed within a polymer. The polymer matrix strongly influences the optical properties of plasmonic nanoparticles. It is imperative to understand the interaction between plasmonic nanoparticles and polymers so that one can …
